Here's why:
* Social animals: Sea lions are highly social animals. They benefit from living in groups for various reasons:
* Protection: Groups offer safety in numbers against predators like sharks and orcas.
* Mating: Colonies provide opportunities for breeding and raising young.
* Communication: Groups allow for sharing information about food sources and potential dangers.
* Learning: Young sea lions learn essential survival skills from older members of the colony.
* Different social structures: The size and structure of sea lion groups can vary depending on the species and location. Some groups may be large and permanent, while others are smaller and more temporary.
* Exceptions: While most sea lions live in groups, there may be instances where individuals live alone, especially during periods of migration or when seeking food.
